C语言表白程序1颜色变化的心

1、这是我在学校的一个小组作业。
2、这道程序经过我一晚上的搜索，借鉴。
3、运行软件：dev c++。
4、代码：（备注：输入yes可以看到结果）

```c
#include 
#include 
#include 
#define I 20
#define R 340
#include 
int main()
{
	char answer[10];
	printf("遇到你\n我才发现\n曾经所有的条件\n似乎都成了我等你的借口\n\n");
	printf("我对你的感情已经决堤\n所以\n请允许我，从今往后映入你\n明媚的眼\n");
	printf("我\n想和你\n耳鬓厮磨，相濡以沫！");
	printf("答应我吧！\n输入yes,你可以看到我的真心\n");
	scanf("%s", answer);
	float y, x, z, f;
	for (y = 1.5f; y > -1.5f; y -= 0.1f)
	{
		for (x = -1.5f; x < 1.5f; x += 0.05f)
		{
			z = x * x + y * y - 1;
			f = z * z*z - x * x*y*y*y;
			putchar(f <= 0.0f ? "*********"[(int)(f*-8.0f)] : ' ');
		}
		putchar('\n');
	}
	long time;
	for (;;)
	{
		system("color a");
		for (time = 0; time<99999999; time++);
		system("color b");
		for (time = 0; time<99999999; time++);
		system("color c");
		for (time = 0; time<99999999; time++);
		system("color d");
		for (time = 0; time<99999999; time++);
		system("color e");
		for (time = 0; time<99999999; time++);
		system("color f");
		for (time = 0; time<99999999; time++);
		system("color 0");
		for (time = 0; time<99999999; time++);
		system("color 1");
		for (time = 0; time<99999999; time++);
		system("color 2");
		for (time = 0; time<99999999; time++);
		system("color 3");
		for (time = 0; time<99999999; time++);
		system("color 4");
		for (time = 0; time<99999999; time++);
		system("color 5");
		for (time = 0; time<99999999; time++);
		system("color 6");
		for (time = 0; time<99999999; time++);
		system("color 7");
		for (time = 0; time<99999999; time++);
		system("color 8");
		for (time = 0; time<99999999; time++);
		system("color 9");
	}
	getchar();
	return 0;
}
